The controller of the portable apparatus 100 may establish a connection of first wireless communication to the communication interface of the wearable apparatus 200 using the communication interface of the portable apparatus 100 in correspondence with the user's selection. For example, the first wireless communication may be wireless communication (for example, short-range wireless communication) having a limited transmission distance (for example, 1 m or less, 10 m or less, 100 m or less, or the like). The portable apparatus 100 and the wearable apparatus 200 may be connected to the first wireless communication having the limited transmission distance. The first wireless communication may be the short-range wireless communication, but is not limited thereto. In addition, second wireless communication may be long-range wireless communication, and may include mobile communication, but is not limited thereto.

When the portable apparatus 100 and the wearable apparatus 200 are connected through BT, the portable apparatus 100 and the wearable apparatus 200 may be connected through a mutually supported profile (for example, an advanced audio distribution profile (A2DP), an audio/video remote control profile (AVRCP), a headset profile (HSP), and a hands-free profile (HFP)).

When the portable apparatus 100 and the wearable apparatus 200 are connected, the controller may transmit portable apparatus information and content (for example, schedule information) to be executed in the portable apparatus 100 to the wearable apparatus 200 through the communication interface.

When the portable apparatus 100 and the wearable apparatus 200 are connected, the controller of the portable apparatus 100 may store the wearable apparatus information received from the wearable apparatus 200 in the storage unit 175. The stored apparatus information of the wearable apparatus 200 may include wireless connection information (for example, including a service set identifier (SSID), an Internet protocol (IP) address, a medium access control (MAC) address, a channel number, a security key, etc.), a product name of the wearable apparatus 200, an ID of the wearable apparatus 200, a MAC address of the wearable apparatus 200, a type of the wearable apparatus 200, a profile of the wearable apparatus 200, a communication scheme of the wearable apparatus 200, etc. The stored content information may include a content ID, a content name, a content type (for example, a computer game or the like), a touch pad application execution command, etc.

The controller of the wearable apparatus 200 may search for the peripheral portable apparatus 100 using the communication interface. The user may select the portable apparatus 100 from a search list (not illustrated) corresponding to a search result displayed on the screen of the wearable apparatus 200. The controller of the wearable apparatus 200 may be wirelessly connected to the communication interface of the portable apparatus 100 using the communication interface in correspondence with the user's selection.

When the portable apparatus 100 and the wearable apparatus 200 are connected, the controller of the wearable apparatus 200 may store the portable apparatus information and content (for example, schedule information) to be executed received from the portable apparatus 100 in the storage unit. The stored portable apparatus information may include wireless connection information (for example, including an SSID, an IP address, a MAC address, a channel number, a security key, etc.), a product name of the portable apparatus 100, an ID of the wearable apparatus 200, a MAC address of the portable apparatus 100, a type of the portable apparatus 100, a profile of the portable apparatus 100, a communication scheme of the portable apparatus 100, etc.

When the portable apparatus 100 and the wearable apparatus 200 are connected, the controller of the wearable apparatus 200 may transmit information of an application (for example, the touch pad application) to be executed using a second communication interface to the portable apparatus 100.

When the portable apparatus 100 and the wearable apparatus 200 are connected, the controller of the portable apparatus 100 may transmit application information corresponding to an application to be executed using the communication interface to the wearable apparatus 200. The application information, for example, may include application identification information (for example, a product name, an ID, a classification code, or the like), state information (for example, execution, standby, stop, etc. of the application) of a corresponding application at a point in time at which the application information is transmitted, etc.

The current state is a state in which the portable apparatus 100 is connected to the wearable apparatus 200.

The controller of the portable apparatus 100 connected to the wearable apparatus 200 may transmit schedule information registered (or updated) in a schedule application corresponding to a shortcut icon 193 f to the wearable apparatus 200. The controller of the wearable apparatus 200 may display a schedule 500 corresponding to schedule information received from the portable apparatus 100 on the screen. In addition, the controller of the wearable apparatus 200 may request the portable apparatus 100 to provide the schedule information. The controller of the portable apparatus 100 may transmit the schedule information corresponding to the request of the wearable apparatus 200 to the wearable apparatus 200.

The controller may display the schedule 500 in a daily, weekly, or monthly form, or the like.

In operation S320 of FIG. 3, a connection to the wearable apparatus is terminated.

Referring to FIG. 5B, a connection between the portable apparatus 100 and the wearable apparatus 200 may be terminated. The controller may detect the termination of the connection to the wearable apparatus 200 using the communication interface. The controller may detect the termination of the connection between the portable apparatus 100 and the wearable apparatus 200 using various methods.

In various embodiments, the controller may detect the termination of the connection between the portable apparatus 100 and the wearable apparatus 200 using the RSSI value. When the communication interface of the portable apparatus 100 receives a radio signal transmitted from the wearable apparatus 200, the controller may calculate the RSSI value. The RSSI may include interference and/or noise of an adjacent channel received by the communication interface of the portable apparatus 100. The controller may periodically calculate the RSSI value (wherein a calculation cycle is, for example, 2 sec and changeable).

The following Table 1 indicates an example of a range of an RSSI value stored in the storage unit of the portable apparatus 100.

TABLE 1 RSSI range [dBm] Connection state Action 0 to −60 Good −61 to −70 OK −71 to −90 Poor Notify Less than −90 Bad Notify

Here, information indicating the range of the stored RSSI value may include a plurality of items indicating the range of the RSSI value, the connection state corresponding to the range of the RSSI value, and the action corresponding to the range of the RSSI value. Those skilled in the art will readily understand that the information is not limited to the above-described items, but may include items (an application to be executed in correspondence with an RSSI value range and a component corresponding to the application to be executed) indicating various information.

The controller may compare the periodically calculated RSSI value with Table 1. According to a comparison result, the controller may determine a connection state between the portable apparatus 100 and the wearable apparatus 200. For example, when the calculated RSSI value is between −71 dBm and −90 dBm, the controller may determine that the connection state of the portable apparatus 100 for the wearable apparatus 200 is poor. When the calculated RSSI value is less than or equal to −91 dBm, the controller may determine that the state of the connection of the portable apparatus 100 for the wearable apparatus 200 is bad.

When the connection state is poor or bad, the controller may determine that the state of the connection between the portable apparatus 100 and the wearable apparatus 200 is the connection termination. When the connection state is poor, the controller may transmit a control command (not illustrated) for outputting an alarm (e.g. a beep) through the speaker or outputting an alarm (e.g. a beep) corresponding to the connection termination to the wearable apparatus 200.

When the connection state is bad, the controller may transmit a control command for outputting a beep through the speaker or outputting an alarm (e.g. a beep) corresponding to the connection termination to the wearable apparatus 200.

The controller may set a threshold RSSI value (which is, for example, −85 dBm and changeable) according to setting of the manufacturer or the user's input. For example, when the calculated RSSI value is −87 dBm, the controller may compare the calculated RSSI value with the threshold RSSI value, and the state of the connection between the portable apparatus 100 and the wearable apparatus 200 may be determined to be the connection termination. Those skilled in the art will readily understand that the RSSI value is changeable according to performance and structures of the portable apparatus 100 and the wearable apparatus 200.

The storage unit may store the calculated RSSI value according to control of the controller. In addition, the storage unit may store the periodically calculated RSSI value according to control of the controller.

In another embodiment, the controller may detect the termination of the connection between the portable apparatus 100 and the wearable apparatus 200 using a BT profile link. When the portable apparatus 100 and the wearable apparatus 200 are connected through BT, a BT profile supported by the portable apparatus 100 and the wearable apparatus 200 among many BT profiles may include an A2DP which is a profile for supporting high-quality stereo audio streaming, an AVRCP which is a profile for supporting a remote control command, an HFP which is a profile for transmitting/receiving the communication voice or performing control, an HSP which is a profile for supporting audio, or a serial port profile (SPP) which is a profile for supporting serial communication.

Those skilled in the art will readily understand that various other profiles as well as the above-described profiles are supported by the portable apparatus 100 and the wearable apparatus 200.

When the portable apparatus 100 and the wearable apparatus 200 are connected through a profile, a profile link connected between the portable apparatus 100 and the wearable apparatus 200 is established. When a link of one profile among a plurality of connected profiles is disconnected, the controller may output a normal connection termination signal. When links of all profiles among the plurality of connected profiles are disconnected, the controller may generate an abnormal connection termination signal.

The abnormal connection termination may occur, for example, when the distance between the portable apparatus 100 and the wearable apparatus 200 exceeds a maximum BT connection distance (which is, for example, 10 m and differs according to a BT version), when a radio signal is weak between the portable apparatus 100 and the wearable apparatus 200 or there is a great amount of noise (for example, underground, inside an elevator, or the like), or when there are a number of obstacles (for example, walls, doors, etc.) between the portable apparatus 100 and the wearable apparatus 200.

When the abnormal connection termination signal is generated, the controller may determine the state of the connection between the portable apparatus 100 and the wearable apparatus 200 as the connection termination. When the abnormal connection termination signal is generated, the controller may transmit a control command (not illustrated) for outputting a beep through the speaker or outputting a beep corresponding to the connection termination to the wearable apparatus 200.

When the connection to the wearable apparatus 200 is terminated, the controller may display a popup window 550 corresponding to the termination of the connection between the portable apparatus 100 and the wearable apparatus 200 on the screen.

The storage unit may store a normal connection termination signal and/or an abnormal connection termination signal according to control of the controller.

In operation S330 of FIG. 3, a signal corresponding to location information is received.

Referring to FIG. 5C, the controller may receive signals from a plurality of GPS satellites 156 through the GPS unit in operation when the state of the connection between the portable apparatus 100 and the wearable apparatus 200 is connection termination. The controller may determine the “connection termination location” of the portable apparatus 100 using the received signal. At the connection termination time at which the connection between the portable apparatus 100 and the wearable apparatus 200 is terminated, the controller may determine the “connection termination location” after receiving signals from a plurality of GPS satellites 156 a plurality of times to correctly measure an outdoor location of the portable apparatus 100.

When the GPS unit does not operate at the connection termination time at which the connection between the portable apparatus 100 and the wearable apparatus 200 is terminated, the controller may execute the GPS unit. The executed GPS unit may receive signals from the plurality of GPS satellites 156 according to control of the controller.

The controller may determine the “connection termination location” using one of a signal received before the connection termination time and a signal received after the connection termination time.

The controller may determine the “connection termination location” of the portable apparatus 100 located indoors using the wireless AP.

When the Wi-Fi (not illustrated) communication does not operate at the connection termination time at which the connection between the portable apparatus 100 and the wearable apparatus 200 is terminated, the controller may activate the Wi-Fi communication of the portable apparatus 100. The controller may receive a signal from the wireless AP using the Wi-Fi communication. At the connection termination time at which the connection between the portable apparatus 100 and the wearable apparatus 200 is terminated, the controller may determine the “connection termination location” after receiving a signal from a wireless AP a plurality of times to correctly measure an indoor location of the portable apparatus 100.

When signals are received from the plurality of GPS satellites 156, the controller may display a popup window 551 corresponding to signal reception from the plurality of GPS satellites 156 on the screen.

The storage unit may store the received signal and/or “connection termination location” according to control of the controller.

In operation S340 of FIG. 3, it is determined whether the portable apparatus moves.

The controller may determine whether the portable apparatus 100 moves. The movement of the portable apparatus 100 may be determined using the communication interface, the camera, the GPS unit, or the sensor unit according to control of the controller. For example, the controller may detect the movement of the portable apparatus 100 using the communication interface and the wireless AP. The controller may detect the movement of the portable apparatus 100 using the signal received from the GPS satellite through the GPS unit. The controller may detect the movement of the portable apparatus 100 using the sensor unit. For example, the controller may detect the movement of the portable apparatus 100 using an acceleration sensor or a motion sensor.

The storage unit may store state information (for example, an ID for history management, a detection sensor name, a detection sensor type, a state of the portable apparatus corresponding to fixation or movement, a detection time, or the like) corresponding to the movement of the portable apparatus 100 or state information (for example, an ID for history management, a detection sensor name, a detection sensor type, a state of the portable apparatus corresponding to fixation or movement, a detection time, or the like) corresponding to the fixation of the portable apparatus 100 according to control of the controller.

When the portable apparatus 100 is fixed, the process proceeds to operation S350 of FIG. 3.

In operation S350 of FIG. 3, location information is transmitted to the wearable apparatus.

When the location of the portable apparatus 100 is fixed, the controller may transmit location information corresponding to the connection termination location of the portable apparatus 100 to the wearable apparatus 200 through second wireless communication. For example, the second wireless communication may be wireless communication (for example, mobile communication using a phone number) in which a transmission distance is not limited. The portable apparatus 100 and the wearable apparatus 200 may be connected through the mobile communication.

When the connection between the portable apparatus 100 and the wearable apparatus 200 is terminated, the controller may transmit location information corresponding to the connection termination location of the portable apparatus 100 to the wearable apparatus 200 through the mobile communication interface 120. The controller may iteratively transmit location information corresponding to the connection termination location of the portable apparatus 100 in a preset cycle (for example, 50 msec).

When a response corresponding to reception of location information corresponding to the connection termination location is received from the wearable apparatus 200 to the portable apparatus 100, the controller may stop the transmission of the location information corresponding to the termination location of the connection to be periodically transmitted.

The controller of the wearable apparatus 200 may receive the location information corresponding to the connection termination location of the portable apparatus 100 through the mobile communication interface.

The storage unit may store the location information corresponding to the connection termination location of the portable apparatus 100 received according to control of the controller.

Referring to FIG. 5D, the controller of the wearable apparatus 200 may display the received location information corresponding to the connection termination location of the portable apparatus 100 on the screen.

The controller may display a connection termination location 511 of the portable apparatus 100 and a current location 512 of the wearable apparatus 200 on the screen through a map application 510. The controller may display a distance difference (for example, 50 m) between the connection termination location 511 of the portable apparatus 100 and the current location 512 of the wearable apparatus 200 through the map application 510. In addition, the controller may display a time duration (for example, 30 sec) from the connection termination time point of the portable apparatus 100 to a current time through the map application 510.

The controller of the wearable apparatus 200 may provide the user with feedback corresponding to the reception of the location information. The feedback provided from the wearable apparatus 200 may be provided as one of visual, auditory, and haptic feedback to the user. The controller may provide the user with one of the visual, auditory, and haptic feedback or a combination of the visual, auditory, and haptic feedback through the wearable apparatus 200.

The visual feedback may be displayed to be distinguished from an object displayed in an application 510 or 520 as a visual effect (for example, a separate image or an animation effect such as a fade applied to a separate image) corresponding to the reception of the location information. The auditory feedback may be output as a sound corresponding to the reception of the location information from a speaker. The haptic feedback may be output from a vibration motor in correspondence with the reception of the location information.

In an environmental setting (not illustrated) of the wearable apparatus 200, it is possible to select and/or change the feedback (for example, at least one of visual, auditory, and haptic feedback) corresponding to the reception of the location information.

The user may input and/or change a feedback providing time (which is, for example, 300 msec and changeable) in which at least one type of feedback is provided to the user.

The user may refer to the connection termination location 511 of the portable apparatus 100 displayed on the screen of the wearable apparatus 200 to find the portable apparatus 100 present in the connection termination location 511. The controller may display a movement path (or a shortest path) from the current location 512 to the connection termination location 511 through the map application 510. The user may move to the connection termination location 511 using the movement path displayed in the map application 510.
